From 57c441bd9ccbea0bf1ec0a417aba40d74bcd8db9 Mon Sep 17 00:00:00 2001 From: Vadim Yanitskiy Date: Sat, 25 Feb 2023 18:04:45 +0700 Subject: [PATCH] gtp: use OSMO_ASSERT() in gtp_new() When using built-in static_assert() [1], gcc v12.2.1 fails: In file included from gsn.c:27: gsn.c: In function 'gtp_new': gsn.c:444:54: error: expression in static assertion is not constant 444 | osmo_static_assert(gtp_T_defs[0].default_val != 0, first_default_val_not_zero); | ^ The reason is likely that gtp_T_defs[] is not const, so it cannot be assert()ed statically. With the current osmo_static_assert() implementation, this assert does nothing. One can change the gtp_T_defs[0].default_val to 0 and the code will still compile.
